排列三012走势图组选 www.gfzd.net Radar level gauge is the use of the signal will be emitted out, and then receive the object reflected back to the signal, and then analyze the level of the signal transmitter and the distance between the principle of this method to work. It is mainly used in areas where it is not possible to contact liquids, slurries and pellets but require continuous measurement of the position of the object, which can play a large role in the presence of volatile temperature and pressure changes or where there is an inert gas. China's current radar level gauge market analysis, different models and grades of products have a certain gap.
To achieve a capacitive level meter feed once completed the calibration of the simple operation; in order to achieve the level of measurement of the strong function and easy to operate the perfect combination, fully reflects the Division I advancing with the times the spirit of innovation and ability. It consists of two parts: sensor and secondary instrument. The sensor on the top of the silo, the probe vertical into the silo, the second instrument on other suitable places. The sensor changes the level of the change into the corresponding electrical pulse signal, remote to the secondary instrument processing, and then use the light column display level height, and a high / low alarm and 4 ~ 20mA transmission output for liquid / Solid material crop level display, alarm, control and remote display or composition system.
Currently on the market the most popular three radar level gauge are guided wave radar level gauge, pulse radar level gauge and intelligent radar level gauge. The basic working principle of the three level gauges is the same, but there are still differences between the three because of the different areas of application.
Technology: The waveguide radar level gauge measurement will not be due to media, temperature, inert gas and other objects affected by the impact; pulse radar level meter launch frequency up to 26GHz, and its signal analysis and therefore more high-speed; intelligent The radar level gauge can convert its own run time through the internal electronics into a level signal, and its highly intelligent time extension method ensures the stability and accuracy of the measurement over a very short period of time.
Performance: guided wave radar level gauge measurement accuracy of 5mm, its range is 60 meters, can withstand 250 ℃ high temperature, 40 kg of high pressure; high frequency radar level meter antenna will be launched in a flash of microwave pulse, After the signal is transmitted, it will be reflected back in an instant, and the speed of the analysis is very fast; the intelligent radar level is that even if the condition is complicated, the echo may be false, it can also use the The latest micro-processing technology and debugging software is very fast and accurate analysis of the correct level of echo.
